The first of these commercials is for what we would call Rock Lords, an '80s Gobot tie-in toyline which was a subline of Machine Robo in Japan (hence dudes shouting "MASHEEN ROBO!" at the beginning).
I have to admit, I have always loved the "dishonest" Japanese toy commercials.
Here's another one, whose only special effects seem to be explosions.
I seem to very dimly remember seeing commercials for something like these way back in my childhood. (There were a lot of vaguely similar toys, admittedly.) This commercial, though, makes the toys look a lot better than most US commercials.
My point? Japanese toy commercials are frikkin' awesome.
...What, you were expecting more of a point than that? Sorry.
